688-0744 or 6880744 Fabco self-locking nut with Dri-Loc #201, a genuine Fabco part from Pro Gear and Transmission. The threads carry a dry locking coating that stays inert until the nut is threaded on, so it resists backing off under vibration and no liquid threadlocker is needed at assembly. Once cured, the coating also helps seal the threads. The factory parts list carries it in the Fabco TC 143 transfer case (item 80, one per assembly) and, as the bearing lock nut, in the TC 270 rear output shaft assembly (item 1, one per assembly). Call us to confirm proper fit for your application.
